[xsl] Fwd: When you give generate-id a nodeset

["Ihe Onwuka ihe.onwuka@xxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

Came across something unexpected while doing the if/else hack to supply a
node to generate-id.

I have <xsl:key match="stuff | morestuff"
use="generate-id(ancestor::tr[predicate]  |
 ancestor::tr[not(predicate)]/preceding-sibling::tr[predicate])"/>

Some data
<wrapper>
<tr pred="true" id="A">
    <stuff/>
    <stuff/>
</tr>
<tr pred="true" id="B">
    <stuff/>
    <stuff/>
</tr>
 <tr pred="true" id="C">
    <stuff/>
    <stuff/>
</tr>
<tr pred="false">
    <morestuff/>
 </tr>
</wrapper>

So here stuff should  take the id of the tr parent and morestuff shouldl
take the id of the tr with id C.

Given that generate-id given  a nodeset only considers the first node I
thought wayhay that will work but it didn't until I included a first node
predicate explicitly like so.

xsl:key match="stuff | morestuff" use="generate-id(ancestor::tr[predicate]
 |  ancestor::tr[not(predicate)]/preceding-sibling::tr[predicate][1])"/>

Should such be necessary?. Only tried it running version 1.0 on  XSLTProc
